Public bug reported:
gcc is giving an apparently spurious warning:
shadow.c: In function ‘create_shadowed_pixbuf’:
shadow.c:16:28: warning: ‘r’ may be used uninitialized in this function
[-Wmaybe-uninitialized]
return ((1 / (2 * M_PI * r)) *
~~~~~~~~~~^~~~
shadow.c:14:1: note: ‘r’ was declared here
gaussian (double x, double y, double r)
^~~~~~~~
It looks like that's impossible to me. The relevant source file is:
